Beyond SaaS, IaaS and PaaS

Most of us are familiar with the SaaS, IaaS, and PaaS business models, sometimes considering them the ONLY cloud models out there. Recently, however, I have been stumbling on blog posts outlining other business models for the cloud. For example, Chirag Mehta of SAP recently wrote about “Emergent Cloud Computing Business Models“. So, are these really alternatives or just a subset of the existing models? Can the enterprise benefit from these new models the same way it does from the traditional “as-a-service” ones?
